Error accessing Addon Scripts/Addon Modules

I get the following error when I access either the Addon Scripts or Addon Modules in my root WHM.

Unable to retrieve modules [an error or timeout occurred while processing this directive]

Now, earlier, when I got this........I came here and saw that the CPanel update server had a hard drive failure......so I thought "Hmmm......maybe it's got something to do with that and I didn't get the full update to Current 42".

So I updated CPanel again (to Current 42).

It worked and I was able to uninstall clamavconnector, which is what I'd been trying to do because it was giving my end users problems uploading stuff and I couldn't find the darn config file despite (even after searching in the forum and doing what was suggested).
